I have an old 486 which used to have a single ide controller card
(with two hard drives connected to it) and a proprietary controller for
a Matushita/Panasonic/Creative 2x CD-ROM. The cd-rom went the way of
hadware heaven and I want to put in another unit.
I figured I would change the ide controler for a dual ide one (ide0
and ide1 on the same board). I tested it using another hard drive I had
lying around (I collect old components :). Booting Linux shows all three
drives hda, hdb and the added hdc on the ide1 connector) but says "hdc:
lost interrupt" and eventually hangs.
A cat /proc/interrupts shows ide0 in irq 14 and ide1 on irq 15.
My questions are:
1. Is there a jumper I could set to correct this (lost interrupt).
2. What is IOCHRDY? Should I enable or disable it (jumper on controler)?
